摘　　要：针对视频水印在共谋攻击中的鲁棒性,在离散余弦变换域,对视频内容特征进行了研究,提出了水印信息和水印位置信息同时关联于嵌入点内容的算法,并给出了水印算法鲁棒性检测实验,实验证明该算法对共谋攻击有良好的鲁棒性。To improve the collusion attack of the video watermark, video content features were studied in domain of diacrete cosine transform, the algorithm in which both watermark information and its position information depend on content of embedded point was presented. Finally, experiment was performed to detect robustness of the algorithm. The result demonstrats that the algorithm is robust to collusion attack.
